He was originally a decent amateur, having a pre-professional dispute with the future Jumbo Tsuruta over team representation in the Japanese collegiate championships.

Quickly frustrated with NJPW's rigid norms, he quit in 1973 and wandered the wrestling circuits of North America.

Nearly two weeks later, he won the vacant Stampede Wrestling International Tag Team Championship with the Dynamite Kid, making him a double champion.

His first stop on his second American excursion is for the NWA's Tri-State territory, where he spent a year wrestling the likes of Wahoo McDaniel, Butch Reed (He was over in Florida), and The Spoiler.

In 1981, he moved east to the Mid-Atlantic territory, where he spent nearly three years there as Ninja, wrestling the likes of Johnny Weaver, Jimmy Valiant, Blackjack Mulligan, Ivan Koloff, Jay Youngblood, Barry Windham, Don Kernodle, Buddy Landell, Leroy Brown, Mike Davis, Lord Alfred Hayes, Iceman "King" Parsons, and Porkchop Cash.

They took part in a league to determine the inaugural IWGP Tag Team Champions; they placed seventh with seven points.

In June 1990, he was back in Japan, this time for Frontier Martial-Arts Wrestling, which was an upstart promotion that specialized in death matches.

In the summer of 1991, Pogo left FMW, because he wanted more interesting matches to compete in, and moved to Wrestling International New Generations (W*ING), where he partook in innovated deathmatches with everyone, ranging from veterans like Kim Duk and Kevin Sullivan to up and coming stars like Mitsuhiro Matsunaga and Yukihiro Kanemura, among others.

His last match as an active FMW wrestler took place at Year End Spectacular on December 11, 1996, teaming with Masato Tanaka, Tetsuhiro Kuroda, and the returning Atsushi Onita to defeat Terry Funk, Hisakatsu Oya, and The Headhunters in what was considered Pogo's retirement match.

After losing the title, he left BJW and briefly returned to FMW to feud with Atsushi Onita one more time, before leaving in November 1998.

Massive blood loss during the second surgery resulted in doctors deeming it too dangerous to continue and it was halted mid-way through.

During the surgery, Sekigawa's blood pressure dropped to the point where he began experiencing an irregular heartbeat, resulting in a cerebral infarction.
